Objects Counting on Mobile Platform in Dusty Environment Through Load Measurement

Abstract

In applications where the electronic systems are required to be used in mobile and dusty environmental conditions, the performance of systems becomes critical with respect to selection of sensors as they need to be done carefully. In such harsh conditions the main objective and challenge is to select suitable sensors and mount the sensors such that high degree of accuracy and reliability is achieved. Our application required to count the number of objects at any instant on a transverse platform mounted on a vehicle that encounters dusty environmental conditions. In our application, we have used load cells with proper mounting to address the specific end use conditions. In this paper we have discussed the selection of sensor, mounting design, related electronic circuitry and its testing. The tests were conducted to count the number of objects on transverse platform through the load measurement. The results show that the design is robust and can work in a dusty and mobile environment with high accuracy.
